| Abstract | ||
| In the present work the specific radioactivity measurements of radionuclides to 238 U,232Th and 40K and some radiological parameters of (10) selected cement samples that available in Iraq markets was determined using NaI (Tl) , The results showed the average specific activity for (238 U, 232Th and 40K ) have been found ( 23.338±0.279Bq/kg , 39.522±0.433 Bq/kg and 153.666±3.477Bq/kg) respectively. while the average values of external hazard index (0.2504±0.0031) ,internal hazard index(0.316±0.003), absorbed dose( 41.522±0.535 nGy/h ), Radium Equivalent (92.62±1.164Bq/kg), The indoor annual effective dose (203.691±2.625 μSv/y) and the outdoor annual effective dose (50.923±0.655 μSv/y). | ||
